JACOB G. MINER, OF NEW YORK, N. Y.

STREET-LAM P.

SPECIFICATION forming part of Letters Patent No; 228,265, dated June 1, 1880.

Application filed October 9, 1879.

To all whom it may concern:

Be it known that I, JACOB Gr. MINER, of New York city, in the State of New York, have invented certain new and useful Improvements relating to Street-Lamps, of which the followin g is a specification.

This invention relates to certain improvements in street-lamps, whereby provision is made for supporting the lamp glass or globe wholly at its upper surface or edge, the said upper edge being confined between a series of arms or other supports formed at the upper part of a vertical standard and the lamp-top, which is rigidly secured to said vertical standard, whereby all outside frame-Work, which would impair the aesthetic appearance of the lamp and obstruct the rays of light, is dispensed with and the top securely fastened, so that in the event of the destruction of the lamp-glass, from any cause whatever, the top will remain intact and uninjured.

As heretofore and ordinarily constructed street-lamps have been formed with an extra frame embracing and supporting the lampglass; but such outer frame interferes with the appearance of the lamp glass or globe, which is usually of an ornamental configuration, and obstructs the rays of light from the burner.

In order to obviate the above-enumerated objectionsthat is to say, to preserve the beauty of the lamp-glass and prevent the obstruction of the rays of light-a lamp has been provided having a seat to receive the lampglass and having the roof or cap supported on the central standard.

The invention consists in the combination, in street-lamps, of acentral vertical standard, provided near its upper extremity with a seat for the upper edge of a lamp-glass, with the top-section roof or cap of the lamp attached to or near the upper terminal of the vertical standard, whereby the said glass is rigidly secured and supported at its upper edge, as and for the purposes more fully hereinafter set forth.

In the drawings, Figure 1 represents a view, partly in side elevation and partly in vertical section, of my improved lamp; and Fig. 2, a detached perspective view of the upper portion of the lamp-glass support, showing the seat and the terminal connection for the top section of the lamp. Fig. 3 represents a bottom view of the top section of the lamp-cap.

Similar letters of reference indicate like parts.

Referring to the drawings, A represents the lamp-supporting post or standard, which may be of the ordinary description, or of any improved construction; and B, the burners of the lamp.

From the burners, at or near their base, ex: tends upwardly a standard, 0, the upper portion of which is provided with a series of radial arms, D, shouldered at their ends, as indicated at D, the shoulders forming seats for the upper edge, F, of the lam p-glass.

From the standard 0 extends upwardly a vertical extension, Gr, screw-threaded externally, to which the top section or cap, H, of the lamp is secured by means of the female screwthreaded crossbar I, forming part of said top section or cap.

It will be seen that, as thus constructed, the lamp-glass is supported wholly at its up per edge between the seat on the central standard and the top section or cap secured to the said standard, and that the top section is securely fastened to the inner standard, so that if the lamp-glass should be broken or injured the top section or cap would remain intact with the central standard.

The cap H is screwed down upon the upper edge of the glass F, so as to bind it firmly between itself and the shouldered arms D D. The screw-connection of the central standardextension, G, to the cap H may be formed in the cap, or by extending the standard up farther it may be screwed into a top nut, E.

Modifications may be made in the form of the details. I can make the central standard with an opening in the center to allow one or more burners to have a central position, or I can extend the central standard up directly and place any required number of burners on short arms outside, care being taken that these burners are never carried so far from the central post as to bring the flame too near the glass.

lVhat I claim is 1. In a street-lamp, the central standard, 0, having a threaded upper portion, Gr, combined with the cross-bar I and cap H, as and my hand this 22d day of September, 1879, in for the purposes herein specified. the presence of two subscribing witnesses.

2. In a street-lamp, the globe F, suspended by its upper edge alone, in combination with 5 the threaded standardeap H, arms D D, and Witnesses:

burner, as specified. H. A. J OHNSTONE,

In testimony whereof I have hereunto set WM. O. DEY.
